Description

  The present invention relates to a sprayer that imparts a sterilizing and deodorizing effect to cooking utensils, tableware, cooking appliances, and other items used in food processing, cooking, and meals.

In recent years, countermeasures against infection by viruses and bacteria such as norovirus and food poisoning bacteria have become increasingly important. In 1996, an outbreak of food poisoning due to enterohemorrhagic Escherichia coli O157 occurred, and many infections have been reported since then. Recently, there are concerns about the occurrence of pandemic (a pandemic of infectious diseases) due to viruses and fungi, such as avian influenza virus that can grow in the human body due to genetic mutation and change to a highly toxic new influenza.
Therefore, it is important to take sufficient measures in advance at companies, homes, and other places where the public gathers so that this situation does not occur.

Here, various technologies for removing viruses and bacteria have been proposed, and examples include a sterilization and deodorization method described in Patent Document 1 and an aerosol product described in Patent Document 2. be able to.
Patent Document 1 discloses a technique in which an aqueous solution containing hypochlorite is adjusted to pH 9 to 12 and sprayed in a mist state having a particle size of 10 μm or less.
Patent Document 2 discloses an aerosol product in which acidic water obtained by electrolyzing water is filled in a container made of a polyester resin together with a propellant.

Japanese Patent No. 3888835 JP 2002-165868 A

However, according to the sterilization and deodorization method described in Patent Document 1, although a strong sterilization effect is obtained, since an alkaline solution having a pH of 9 to 12 is sprayed, sufficient caution is required for use. It wasn't something that everyone could use easily.
Moreover, although the aerosol product of patent document 2 uses the acidic water obtained by electrolyzing water, it uses the strong acidic water of pH 2.5, and when it sprays on a metal, it will corrode. For this reason, it was necessary to handle with some care.

Furthermore, generally, a sterilizing agent using alcohol as a component having a sterilizing effect is also known.
However, since alcohol is highly volatile, it may evaporate before a sufficient disinfection effect is obtained. In addition, since oil is removed at the same time as sterilization, it may cause rough skin and is difficult to use. Furthermore, alcohol is said to be unsuitable for sterilization where there is a lot of water, and was not flexible.

In addition, in cooking-related facilities such as cafeterias and kitchens, agriculture, fisheries, and dairy farming, as a countermeasure against norovirus and food poisoning bacteria, cooking utensils, tableware, cooking equipment, and other items used for processing, cooking, and eating food Disinfection with alcohol is widely performed.
However, the method of sterilizing food-related articles with alcohol as described above has a problem in that food or tableware has an alcohol odor. For this reason, a sterilization method more suitable for foods has been demanded.

Here, “sodium hypochlorite” which is a kind of hypochlorite is diluted with water and further adjusted with “dilute hydrochloric acid” to make “hypochlorous acid” safe and harmless to the human body. Water ". “Sodium hypochlorite”, “hydrochloric acid”, and “hypochlorous acid water” are all ingredients defined as food additives by the Ministry of Health, Labor and Welfare. It is an environmentally friendly ingredient that returns to water. In addition, by using “dilute hydrochloric acid” as described above, by adjusting the pH of hypochlorous acid water to a pH close to the skin, it is possible to use it safely while having a high sterilizing effect by hypochlorous acid. Can do.
Further, by making the concentration of hypochlorous acid in the hypochlorous acid water a constant concentration, it is possible to sterilize the above-described cooking utensils and cooking equipment. Further, according to the sterilization with hypochlorous acid water, there is no problem that the odor of alcohol is attached to food, tableware, etc. as in the sterilization method using alcohol.

Therefore, the present inventor has intensively studied, and by applying such "hypochlorous acid water" to aerosol products at a specific concentration, it is safe and odorless even if sprayed directly on cooking utensils or tableware, The present invention has been completed by conceiving that a product excellent in sterilization effect can be provided.

It is set as the structure filled with the hypochlorous acid water whose density | concentration of an acid is 50-100 ppm.
In addition, the sterilizing and deodorizing sprayer of the present invention is designed to spray hypochlorite water onto cooking utensils, tableware, cooking equipment, and other items used in food processing, cooking, and meals, to inactivate and remove viruses. It is preferable to use it for deodorizing bacteria.
Moreover, it is preferable that the sterilization deodorizing sprayer of the present invention is an aerosol type sterilization deodorizing aerosol type filled with non-flammable gas together with the above hypochlorous acid water.

Further, the disinfecting and deodorizing sprayer of the present invention comprises a container body filled with the hypochlorous acid water, and an injection unit for injecting the hypochlorous acid water from the inside of the container body to the outside. It is preferable that the main body and the injection portion are made of resin.
Furthermore, it is preferable that the disinfecting and deodorizing sprayer of the present invention is such that hypochlorous acid water and incombustible gas are filled in an aerosol container having acid resistance and ultraviolet resistance.

  ADVANTAGE OF THE INVENTION According to this invention, the disinfection deodorizing sprayer which has the virus inactivation and disinfection deodorizing effect with respect to the goods used at the time of processing of cooking utensils, tableware, cooking appliances, and other foods, cooking and meals is provided. It becomes possible.

The nebulizer for sterilization and deodorization of the present invention is obtained by diluting sodium hypochlorite with water and adding dilute hydrochloric acid to adjust the pH to slightly acidic, and the concentration of hypochlorous acid is 50 to 100 ppm. It is characterized by being filled with the following hypochlorous acid water.
Hereinafter, although the aerosol type embodiment will be described in detail as the nebulizer for decontamination and deodorization of the present invention, the present invention only needs to have the above features, and is not limited to the configuration of the aerosol type embodiment. Absent.

  As shown in FIG. 1, the sterilization / deodorization aerosol of one embodiment of the present invention includes a container body 1 and an injection unit 2, and preferably includes a container lid 3. The container body 1 is filled with contents 10.

(Container body 1)
The material of the container body 1 of the aerosol container in the sterilization / deodorization aerosol of this embodiment is suitable for stable storage of hypochlorous acid water, and the container body 1 can be used as a pressure resistant container when filled with a propellant. It is preferable. For this reason, it is preferable to use a resin material as the material of the container body 1, and for example, a polyester resin such as a PET (polyethylene terephthalate) resin, a polyethylene naphthalate resin, or a polybutylene terephthalate resin can be suitably used. In addition, as materials for the container body, thermoplastic resins such as polypropylene, polytetrafluoroethylene, engineering plastics and super engineering plastics, and thermosetting resins such as thermosetting polyimides, epoxy resins and unsaturated polyester resins Etc. can also be used. Furthermore, what consists of several resin, fiber reinforced plastics, such as glass fiber reinforced plastic and carbon fiber reinforced plastic, can also be used.
For example, a breathable resin such as PET can be used alone as the material of the container body 1, but a coating agent such as a fluororesin is applied to the inner surface of the container body 1 so that the filled content does not change. It is more preferable to coat.

In addition, hypochlorous acid water has the property of returning to water by changing its components when exposed to ultraviolet light. For this reason, the container body 1 is preferably made of an ultraviolet resistant material. For example, it is preferable to use a polyester resin blended with titanium oxide, a light shielding agent, or the like. However, since hypochlorous acid water can be decomposed by titanium oxide, it is preferable not to add titanium oxide to the inner layer of the container body 1.
In addition, even if hypochlorous acid water is decomposed, no harmful decomposition products are generated, and water and very little salt are generated.

[Container upper part 1-1]
An injection unit 2 is attached to the container upper part 1-1 in the container body 1. This container upper part 1-1 can be formed integrally with the container main body 1, and can also be comprised as another component. The container upper part 1-1 configured as a separate part may be called a mountain cup, and is attached to seal the opening after filling the aerosol container with the contents.
It is preferable that the container upper part 1-1 is also provided with acid resistance and ultraviolet resistance similarly to the container body 1. When the container upper part 1-1 is formed of a separate part from the container main body 1, it is possible to form the container upper part 1-1 using, for example, aluminum, but it is more preferable to use the same material as the container main body 1. preferable.

(Injection part 2)
The injection unit 2 includes an injection button 2-1, a valve 2-2, and a dip tube 2-3.
When the injection button 2-1 is pushed and the valve 2-2 is opened, hypochlorous acid water is pushed by the compressed gas filled in the container body 1, and is discharged to the outside through the dip tube 2-3. At this time, hypochlorous acid water is jetted in a mist state from the dip tube 2-3 through the nozzle in the jet button 2-1. Thereby, according to the aerosol product of the present invention, hypochlorous acid water can be injected as a dry mist shower.

  It is preferable that the material of the injection unit 2 also has acid resistance and ultraviolet resistance. For example, polyester resin such as high density polyethylene, polypropylene, PET (polyethylene terephthalate) resin, polyethylene naphthalate resin, polybutylene terephthalate resin, Thermoplastic resins such as polytetrafluoroethylene, engineering plastics and super engineering plastics, and thermosetting resins such as thermosetting polyimide, epoxy resin and unsaturated polyester resin can be used.

Furthermore, it is also preferable that the spray button 2-1 in the sterilization / deodorization aerosol of the present embodiment is provided with an elongated nozzle and sprayed with hypochlorous acid water from the tip of the elongated nozzle. If it does in this way, hypochlorous acid water can be sprayed appropriately also to the clearance gap etc. of the cooking tool of a complicated shape, a cooking appliance, etc., for example, and it becomes possible to fully disinfect and deodorize.
In addition, in the sterilization deodorizing aerosol of this embodiment, it is possible to use a spray method to spray hypochlorous acid water without filling the container body 1 with a propellant. In this case, the injection unit 2 can be omitted.

(Container lid 3)
The container lid 3 in the sterilization and deodorizing aerosol of the present embodiment is fitted or screwed to the container upper part 1-1 in order to protect the injection unit 2. The material of the container lid 3 is not particularly limited, but the same material as the container body 1 described above can be used.

In the case where the propellant is filled, in the figure, the gas phase portion inside the container body 1 is filled with the propellant, and the liquid layer portion is filled with hypochlorous acid water. In the present invention, when the propellant is filled, a non-combustible compressed gas such as nitrogen gas or carbon dioxide gas is used as the propellant, so that the gas does not dissolve in the liquid layer and the gas pressure is not reduced. It is preferable to use for. As described above, an aerosol for spraying hypochlorous acid water using a spray method without filling the container body 1 with a propellant is also included in the sterilization deodorizing aerosol of the present invention.

[Hypochlorous acid water]
The hypochlorous acid water in the sterilization deodorizing aerosol of this embodiment can be obtained by diluting sodium hypochlorite with water and adding diluted hydrochloric acid to adjust the pH to slightly acidic. The reaction formula is shown below.
NaClO + H ₂ O → HOCl + NaOH
HOCl + NaOH + HCl → HOCl + NaCl + H ₂ O

Sodium hypochlorite is a food additive used for sterilization of foods, and general ones can be used. Further, hypochlorous acid water obtained by diluting sodium hypochlorite with water is a food additive used for sterilization of food. Hydrochloric acid is also a food additive, and common ones can be used.
Hypochlorous acid water obtained by simply diluting sodium hypochlorite with water has a pH of about 7-8, but hypochlorous acid water in the sterilization deodorizing aerosol of this embodiment is diluted hydrochloric acid. Is added to produce a slightly acidic solution having a pH of about 5 to 6.5. If the pH of hypochlorous acid water is set in this way, a high sterilization effect by hypochlorous acid (HOCl) can be obtained.

  Further, if the pH is further reduced, chlorine gas is generated, which is not preferable. If the pH is set to 6.5 or more, the abundance of hypochlorous acid (HOCl) is lowered, and the effective chlorine abundance is lowered. In general, in a state where sodium hypochlorite is simply diluted with water, the cell membrane of pathogenic bacteria is difficult to break and a sufficient sterilizing effect cannot be obtained. On the other hand, according to slightly acidic hypochlorous acid water having a pH of about 5 to 6.5, the cell membrane is broken, and hypochlorous acid (HOCl) can permeate the lipid bilayer membrane of the pathogen. It can be killed.

  Hypochlorous acid water was reported by the Food Safety Committee in January 2007 as “It is considered that there is no concern about safety when it is removed after use and before completion of the final food”. Therefore, it is considered that there is no problem in safety even when used for sterilization of cooking utensils, tableware, cooking appliances and the like.

The concentration of hypochlorous acid in the hypochlorous acid water filled in the sterilization and deodorizing aerosol of the present embodiment is based on cooking utensils, tableware, cooking equipment, and other items used for processing food, cooking and eating. From the viewpoint of the sterilization effect, it is preferably 50 to 100 ppm. If the concentration is 50 ppm, many bacteria and viruses such as Escherichia coli and food poisoning bacteria can be sterilized within 1 minute except for spore bacteria (spore bacteria can also be sterilized within 2 minutes), This is because a sufficient sterilizing effect can be obtained even if the concentration is not higher than 100 ppm.
From the same viewpoint, it is more preferable that the concentration of hypochlorous acid in the hypochlorous acid water is 50 to 80 ppm.

Further, it has been reported that hypochlorous acid water shows a higher sterilizing effect at a relatively high temperature, and that the sterilizing effect at 40 ° C. is six times the sterilizing effect at 20 ° C.
In addition, you may use what was obtained by electrolyzing salt solution, seawater, etc. as hypochlorous acid water with which the sterilization deodorizing aerosol of this embodiment is filled.

Next, the effect and safety of hypochlorous acid water filled in the sterilization deodorizing aerosol of this embodiment will be described in more detail.
First, the virus inactivation effect will be described. About the hypochlorous acid water with which the aerosol for sterilization and deodorization of this embodiment is filled, a virus inactivation test was conducted by the Japan Food Analysis Center. The test method is as follows.

100ml vitamin solution for MEM 30ml
20% 10% albumin
0.25% trypsin 20ml

5. Preparation of virus suspension (1) Cell culture Using cell growth medium, the used cells were cultured in a single layer in a tissue culture flask.
(2) Inoculation of virus After the monolayer culture, the cell growth medium was removed from the flask and inoculated with the test virus. Next, a cell maintenance medium was added and cultured in a carbon dioxide incubator (CO ₂ concentration: 5%) at 37 ° C. ± 1 ° C. for 1 to 5 days.
(3) Preparation of virus suspension After culturing, the morphology of cells was observed using an inverted phase contrast microscope, and it was confirmed that morphological changes (cytopathic effect) occurred in the cells. Next, the culture solution was centrifuged (3000 r / min, 10 minutes), and the resulting supernatant was diluted 10-fold with purified water to obtain a virus suspension.

6). Test operation 0.1 ml of the virus suspension was added to 1 ml of the sample and mixed to obtain a working solution. It was allowed to act at room temperature and was diluted 10-fold with cell maintenance medium after 30, 60, 90 and 120 seconds. Purified water was tested in the same manner as a control, and measurement was performed at the start and after 120 seconds.

7). Measurement of virus infectivity titer Using cell growth medium, the cells used were monolayer cultured in a tissue culture microplate (96 wells), then the cell growth medium was removed and 0.1 ml of cell maintenance medium was added. Next, 0.1 ml of the working solution dilution was inoculated every 4 holes and cultured in a carbon dioxide incubator (CO ₂ concentration: 5%) at 37 ° C. ± 1 ° C. for 4-7 days. After culturing, the presence or absence of cell morphological changes (cytopathic effect) was observed using an inverted phase contrast microscope, and the 50% tissue culture infectious dose (TCID ₅₀ ) was calculated by the Reed-Muench method to determine the virus per ml of working solution. Converted to infectious titer.

The result is shown in FIG. In the figure, TCID ₅₀ (median tissue culture infectious dose, 50% tissue culture infectious dose) is a logarithmic value of TCID ₅₀ per 1 ml of working fluid. At the start, the control TCID ₅₀ immediately after the start of the action was measured and set as the start. Further, <50 indicates that no detection is performed, and-indicates that the test is not performed.
As shown in the figure, it can be seen that in the control, the virus grew after 120 seconds, whereas in the specimen, the virus was inactivated after 30 seconds.
Thereby, it was confirmed that the hypochlorous acid water with which the sterilization deodorizing aerosol of this embodiment is filled has a virus inactivating effect.

  Next, the sterilization effect of hypochlorous acid water filled in the sterilization / deodorization aerosol of this embodiment will be described. This test was also conducted by the Japan Food Analysis Center. The test method is as follows.
